Last winter, our company undertook a groundwater monitoring project. Below are some pictures and videos from the installation process of this project. In our project plan, we adopted the Beidou satellite communication and navigation system, with the integrated telemetry water level gauge as the core monitoring equipment. The Beidou system can transmit groundwater monitoring data to the big data platform in real time through short message service and has an alarm function.

During the project implementation, our technical personnel often had to face various challenges such as long distances over mountains and rivers, as well as extreme heat and cold. Tailoring solutions for clients and helping them solve difficult problems are our arduous yet glorious missions. Client satisfaction has always been our ultimate pursuit.

As a space-based communication method, Beidou short message communication inherits all the advantages of satellite communication, such as 24/7 service, wide coverage, and high reliability. In addition, it boasts the following unique advantages:

• Fast Response: The delay for short message communication is only about 0.5 seconds, and the delay for point-to-point communication ranges from 1 to 5 seconds.

• Strong Anti-Interference Ability: It utilizes S/L band satellite transmission, and the signal can penetrate the stratosphere and troposphere, ensuring stable communication even under extreme weather conditions.

• Low Equipment Cost and High Cost-Effectiveness: It has low equipment requirements, affordable prices, and outstanding overall cost-effectiveness.

On the road of project advancement, we fear neither high mountains and long distances nor extreme heat and cold. Every step showcases the tenacity and dedication of our technology. We have invested countless efforts in carefully planning solutions for clients. When facing difficult problems, we are always the most solid support for our clients, working together to overcome challenges. Because we deeply understand that our clients' satisfied smiles are the most dazzling trophies and the warmest light on our journey.

On this glorious yet arduous path, we take pleasure in our work, driven by our relentless pursuit of excellent service.
